Cast Alnico magnet is composed primarily of Aluminum, Nickel, Cobalt, Copper and Iron. It has very good corrosion resistance and high temperature operation.Although other magnetic materials offer greater energy and coercivity values, the high remanence and thermal stability of AlNiCo makes it the most effective magnetic material for certain applications, like generator, microphone, lifting, voltmeter and measuring instruments. It is widely applied in high stability fields like aerospace, military, automobile and security systems.
ALNICO MAGNET APPLICATIONS:
Holding magnets , Sensors and transformers, Security systems , Relays, Chucks, Instrumentations, Magnetic switches, Safety Controls, Motors and Generators, Receivers, Telephones, Microphones, Bell ringers, Loudspeakers. Key Advantages Of Cast Alnico Magnets: · Excellent temperature stability · Strong corrosion resistance · Excellent capacity · High density and magnetic properties · Shorter production lead time · Temperature factor of Br is the smallest among all the permanent magnets · Cast Alnico magnets can be produced in relatively complex shapes · Tooling for cast Alnico magnets is relatively low, since sand molds are generally used for the casting process Typical Magnetic Properties | Grade | MMPA Equivalent | Br | Hcb | Hcj | (BH)max | Remark |
